The KDSS hydraulic suspension system can develop leaks at the hydraulic lines and accumulators, especially in areas with road salt. The system helps reduce body roll on-road while allowing articulation off-road. Corrosion of the KDSS lines is common in northern states. Repairs typically run $300-$4,000. Severity: medium.
The A/C compressor can fail prematurely, often sending metal debris throughout the system. When the compressor fails, the entire A/C system typically needs to be flushed and the condenser, drier, and expansion valve replaced along with the compressor to prevent repeat failure. Repairs typically run $1,200-$2,500. Severity: medium.
The starter on 2010-2022 4Runners is prone to corrosion, and if corrosion migrates into the starter relay/solenoid contacts it can cause intermittent no-crank (a single click or nothing on key turn) and, in some cases, additional driveability gremlins. Because the starter sits lo… Repairs typically run $150-$500. Severity: medium.

On higher-mileage 4Runner automatics owners report harsh/abrupt shifts, jerky 3-2 downshifts, unstable RPM blips while coasting near 40 mph, and delayed engagement.

A clunk or pop may be heard from the steering column area when turning the wheel, especially at low speeds or when going from left to right.
